FYI, the critical issue in e-mailing photo files is not the physical 
dimensions.  It's the file size.  While overall dimensions can be a 
factor, the main control is the amount of compression applied to 
reduce the file size for e-mailing (often inaccurately referred to as 
"Quality").

Many programs, like Picasa, adopt reasonable standards to produce 
results that will work in most situations, so users don't have to be 
bothered with details like resolution, JPEG compression, and pixel 
dimensions.  However, at some point in your photo e-mailing efforts 
it will be necessary to know two pieces of information -

1) How big is the file you are trying to e-mail?

2) What is the size limit imposed by the recipient (if any)?

In our case, the recipient is the rhodes22.org mailing list 
software.  Currently that size limit appears to be around 5Mb.  But 
that doesn't sound right to me because people have reported smaller 
attachments not getting thru.  In any case, I believe 5Mb is overly 
generous and that is likely to change in the future.  Also, the water 
gets muddy if you use the nabble.com interface, because it has its 
own set of rules (as yet unknown to me and almost certainly different) .

More details when I have them.

Cheers!
